Examinations were made on the components of Lycopodium serratum THUNB. var. thunbergii MAKINO (Japanese name Hosoba-Togeshiba) from Mt. Hira in Shiga Prefecture. A new triterpene was isolated from the neutral fraction and named serratendiol, C30H48(OH)2, m.p. 300° (diacetate, m.p. 336-338°, [α]D29+18.8°(c=2.34, CHCl3)), with serratenediol monoacetate, C30H48(OH)OCOCH3, m.p. 319-320°, [α]D10-5.7°(c=1.06, CHCl3).
New alkaloids were isolated from the basic fraction and named serratinine, m.p. 244-245°, [α]D8-27.8°(c=1.44, EtOH), C12H17(≡N)(=CH-CH3)(-CH2-CO-)(OH)2, serratine, m.p. 253°, C17H27O3N, and serratanine perchlorate, m.p. 239-241°(decomp.), [α]D12-29.3°(c=0.512, EtOH), C11H19O2N⋅HClO4. Known alkaloids, lycodoline (I) and lycodine (II) were also isolated and identified.
